The Snyder Industries 1300 Gallon HDPE Vertical Liquid Storage Tank is a white, polyethylene vertical storage tank built to ASTM D1998 wall-thickness sizing for above-ground water service, with a 1.9 specific-gravity wall rating. It stands 87 inches tall on a 72 x 72-inch footprint, so it holds a full 1,300 gallons of water in a compact circular base. Filled with water it carries roughly 10,842 pounds, while the 1.9 SG wall gives it a contents ceiling near 20,600 pounds - denser-liquid headroom most water tanks do not have. If you are sizing a vertical storage tank for a building, a yard, or a remote site, this is the kind of HDPE tank that makes the most of a small pad.
Does it work for your install?
The footprint is 72 x 72 inches and overall height is 87 inches - confirm both door and ceiling clearance before delivery, since this is a tall vertical tank. The molded fittings, shown on the technical drawing on this page, include a flange, an 18-inch PE threaded and vented lid, and a manway with 15-inch interior access for inspection and cleaning. Those fitting positions and thread sizes are fixed by the mold, not field-adjustable, and the gaskets and mating flange hardware are sized to those molded fittings - so read the drawing against your plumbing plan and confirm gasket and thread size before you buy any line, bulkhead, or fittings. For volume planning against your actual draw and refill cycle, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit.
The 1.9 SG margin - and how to use it
Rated to 1.9 specific gravity with a contents ceiling near 20,600 pounds against roughly 10,842 pounds full of water, this Snyder vertical carries far more density margin than a commodity 1.0 to 1.5 SG water tank. That future-proofs it for heavier liquids within compatible limits. The margin does not mean fill it to the brim with a heavy liquid, though - freeboard still governs the volume you can actually use, which is laid out in our guide on Snyder freeboard sizing per ASTM D1998.
Weight, pad, and the mistake to avoid
At about 10,842 pounds full of water, this tank needs a level, engineered base - not bare soil or a few patio blocks. A flat, fully supported pad sized to the 72 x 72-inch footprint is what keeps the wall from stress-cracking over years of fill-and-draw cycling. The single most common mistake on a tank this size is undersizing or sloping the pad; for the framework on getting that right, see our guide on concrete pad sizing for above-ground polyethylene tanks. Wall thickness on HDPE verticals follows ASTM D1998 sizing logic, and the most overlooked failure zone is the vapor-saturated headspace above the liquid line - worth understanding before service, covered in our piece on HDPE tank wall thickness at the headspace. For fire-protection storage, the same vertical tank slots into a private fire-water reservoir - see fire-water reservoir tank design for rural and remote sites.
Freight
This Snyder vertical ships LTL freight from the Chowchilla, California plant, quoted live to your ZIP code rather than bundled into the list price. Get an exact number before you order with our Freight Cost Estimator, or call 866-418-1777 and we will quote it for you and confirm delivery details. Tell us about dock access or a liftgate need when you quote - on a tank this size, that is the difference between a smooth delivery and a surprise at the curb.
